Session and Storage Settings

{
  "cleanupPeriodDays": 14,
  "autoMemoryDirectory": "~/my-memory-dir",
  "plansDirectory": "./.claude/plans"
}

cleanupPeriodDays — delete sessions inactive for more than N days (default: 30). Set to 0 to delete ALL transcripts at startup and disable persistence entirely. When 0: no new .jsonl files written, /resume shows nothing, hooks get empty transcript_path.
autoMemoryDirectory — custom directory for auto memory storage (~/ paths supported). NOT allowed in project .claude/settings.json — user/policy settings only.
plansDirectory — where plan files are stored, relative to project root. Default: ~/.claude/plans.
